Blog page not displaying correctly

Hi Guys. Our Easyblog was working fine until someone went to try to publish a new post this morning, now the whole blog page is not displaying correctly with either the blog posts or the latest posts module. Easyblog isn't behaving as expected either. We can't work out what has gone wrong. It was working fine first thing this morning. Nothing has been updated or anything since then...just one of the staff trying to post a new blog... we are at a loss. Hope you can help us out.

Sarah.
